摘要:
为获取植物激素促进多花黄精Polygonatumcyrtonema切块根茎发芽、出苗和植株生长的理想配方，在杉木Cunninghamialanceolata林下开展了6-苄氨基嘌呤（6-BA）、吲哚乙酸（IAA）、赤霉素（GA3）3种植物激素混合溶液共12个处理的多花黄精切块根茎发芽对比试验，并根据根茎发芽数、新根数、出苗率、植株高、地径粗和叶片数6个指标在1%统计学水平的随机区组单因素“Dunn-Sidak法”多重比较结果，优选出合理的催芽配方。结果表明，不同植物激素处理均对多花黄精切块根茎发芽数、新根数、出苗率、植株高、地径粗和叶片数均造成极显著影响（P＜0.01），优选出的“150mg·L-16BA+100mg·L-1IAA混合溶液浸泡1h，再经42500倍GA3溶液处理20min”（D1）、“150mg·L-16BA+100mg·L-1IAA”混合液浸泡3h后，再经“42500倍GA3溶液处理20min”（D3）、“150mg·L-16BA溶液浸泡2h”（A2）三个处理，能显著地促进多花黄精切块根茎发芽、出苗和植株生长，3个处理的平均根茎新芽数为1.29~1.82个·段-1，平均新根数为3.48~6.92条·段-1，平均出苗率为67.59%~86.74%，平均地径粗为0.21~0.22cm，平均植株高为19.56~21.43cm，平均叶片数为5.43~6.19片·株-1，与CK相比，新芽数增加了26.47%~78.43%，新根数增加了40.32%~179.03%，出苗率提高了21.25%~87.18%，地径粗增加了23.53%~29.41%，植株高增长了13.7%~24.67%，叶片数增加了5.23%~19.96%。以上结果表明，合理的6BA+IAA+GA3配方和浸泡时间，能显著提高多花黄精切块根茎发芽、出苗和植株长势。
Abstract:
In June 2020, broadcast preparation of oil was carried out under pure Cunninghamia lanceolata stand planted in 1988 in Jingning, Zhejiang province. In July 2020, wild 1-2 year Polygonatum cyrtonema rhizomes were cut for experiment of 6-Benzylaminopurine (6-BA), indoleacetic acid (IAA), gibberellin (GA3) and mixed solution of the three treatment and seedling cultivation by single factor. In April 2021, investigations were implemented on germinations, new root, seedlings, height and ground diameter and seedling leaves of cut. The result demonstrated that different plant hormone treatments had significant effect on rhizome germination, new root, emergence rate, seedling height, ground diameter and leaf number (P <0.01). The cut treated 1 hour with mixture of 150 mg/L of 6BA + 100 mg/L of IAA mixture, then 20 minutes with 42 500-fold GA3, 3 hours with mixture of 150 mg/L of 6BA + 100 mg/L of IAA, then 20 minutes with 42 500-fold GA3, 2 hours of solution of 150 mg/L of 6BA, had significantly more rhizome germination, seedling emergence rate and seedling growth. Each cut had average 1.29-1.82 new shoot in rhizomes, 3.48- 6.92 new root, 67.59%-86.74% emergence rate, 0.21-0.22 cm ground diameter, 19.56-21.43 cm height, 5.43- 6.19 leaves. Compared with CK (treated by water), the number of new buds increased by 26.47%-78.43%, number of new roots by 40.32-179.03%, emergence rate by 21.25%-87.18%, ground diameter by 23.53%-29.41%, height by 13.79%-24.67%, number of leaves by 5.23%-19.96%.
